Cheats & Lies: Shania Twain & Mutt Lange Split

Shania Twain and husband-producer Robert "Mutt" Lange are splitting up after 14 years of marriage. The 42-year-old Canadian country superstar and 59-year-old Lange married in 1993 and have a 6-year-old son named Eja."It's just an unfortunate thing that's happened," Lange said shortly after the couple's separation was announced Thursday. "It's literally just a growing apart, that's all."
A source close to Twain also reports that the singer didn't expect the split. "She's devastated. She's getting through it with a very close-knit group of family and friends."
But sources close to the couple claim that there was another woman involved: Marie Ann Thiébaud, a longtime secretary and manager of the couple’s chateau in Switzerland.
A source tells People.com, “Mutt and Marie Ann left their spouses for each other and are still in a relationship.” But Lange denies the claims, insisting that, “it’s absolutely not the reason [for the separation],” and he has also blasted talk of him being in a romantic relationship with Thiébaud: “I’m not, no,” he said. “It’s not true.”
Liar... if the split was sudden and devastating for Shania, it's obvious he was cheating!! Cheater, liar and stupid for letting a woman like that go...
